DAVID VAUGHAN, OF BEMSEN, NEW YORK.

MACHINERY FOR JOINTING STAVES.

T 0 all 'whom t may concern Be it known that I, DAVID VAUGHAN, ofRemsen, in the county of Oneida. and State of New York, have inventedcertain new and useful Improvements on Machinery for Jointing Staves forHo-gsheads, Casks, Tubs, &c.`; and I hereby do declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accom panying drawing, forming a part of thisspecication, in which- Figure l, is an end view; Fig. 2, a top view ofclamp for bevels, Fig. 8, top view of clamp for straight edge staves,Fig. 4L, a top view 'of the guide rails and jointer, Fig. 5, a side viewof the jointer for straight edged sta-ves, placed vertically, Fig. 6, alongitudinal view of the frame and guide rail. The same letters indicatelike parts on all the figures. Fig. 7 is a plane stock for windingstaves.

The nature of my invention consists in providing a shaving cutter on aslide, which has a depression at the middle where the shaving tool issecured, to shave the one half of the taper on the edge of the stavefrom the bilge to the end, by the shaving too-l cutting in onedirection, and to shave the other taper from the bilge to the end of thestave in the opposite direction.

My invention furthermore consists in providing side guide rails with adepression in the middle of them to correspond with the depression inthe middle of the jointer slide, and this depression and the side railsto be employed in combination with the slide and clamps, or a clamp toguide the stave to the action of the shaving knife, to shave the edge ofthe staves at an angle, to produce any edge taper on the stave forcasks, or barrels of different diameter.

My invention further consists in providing a ,clamp with a movable jawJ, to secure the stave between it and the stationary jaw J1, the saidjaw being opened and closed by pushing it backward and forward againstthe side pressure of stationary pins, to exert a great power to retaincrooked staves and an easy plan to take out and put in the stave.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

I make a stoutl frame of the most desirable form with upright and crosspieces A, A. B, B, are the cheeks of the jointer or shav- These cheeksare longitudi to rest on, and attached below to strong set screws movingin holes for that purpose in the cross timber A, to raise and lower thecheeks B B, as may be desired, and there may be a graduated scale toindicate the height to which the said cheeks may be elevated, or viceversa. O, C, is the plane stock. It is placed between the cheeks B7 B,and it may be made to slide bet-Ween them, by forming it like Fig. 5, (aa.) being slots to slide on guide bars, or rollers extended through theslots, or it may be made to run and be guided in a groove on the innersides of the cheeks. D, D, are metal plates extending nearly from themiddle of the plane stock, with a gradual elevation to the outer ends (eE is the shaving knife. It is secured in the stock like the common planeiron, and projects above t-he face of the stock. It is placed to shaveas represented in Fig. 4.

By this arrangement of the plane and construction of the stock, theknife E, will shave a stave that may be drawn against it from the bilge,and by turning the said stave around and drawing it against the knife inthe other direction (opposite) the taper will be cut on the edge of thestave from the middle or bilge to the ends. The stave is placed in aclamp constructed to run upon side guide rails on the frame, to guidethe stave to the action of the knife, for the purpose of cutting thebevel or feather on the edge of the stave, which is more fully describedas follows: F, F, are side guide rails. They are secured by screws tothe longitudinal sleepers I-I H; f) are the screws. These guide railsare made of metal with two beads or heads h1 71.2 on them. The one h1has a depression in the middle as seen in Fig. 6. The other 7a2 isstraight. The former is the guide rail for bilge staves, the latter (h2)for straight staves. The said rails can be changed in position, to allowthe straight bead h2 to be placed in the position of h1 and vice versa,by the screws by which they are secured to the sleepers.

In conjunction with the tool or plane stock and the guide rails, Iemploy a clamp to hold the stave firmly to the shaving action of theknife, and to be guided on the guide rails, correctly to the action ofthe knife, to shave the desired feather on the edge of the stave. Figs.2 and 3 are top views of the clamp. They are both constructed on thesame principle, only Fig. 2, represents the clamp as made to retain thecrooked staves and Fig. 3, to hold straight staves. J1 J2 are jaws ofthe clamp. J 2 is a stationary jaw; J2 is a movable jaw. The jaw J2 hasslots in it indicated by the dotted lines. WW are transverse bars whichpass through these slots, and allow the said jaw J2 to move backward andforward; t t, are two inclinations on the jaw J2 which terminate innotches V V. Q Q, are two fixed pins passing through the bars W W andagainst these pins the inclines t t, press, in a greater degree, if thejaw J2 be pushed to the right, the inclines acting thus as wedgesagainst the pins Q, squeezing the stave S (as represented in Fig. v2)between the jaws. To release the stave the jaw J2 Fig. 2, has just to bepushed to the left. R R, are two concave metal runners (secured in anyof the known ways in the clamp), of the form represented l in Fig. 1,which also represents the manner of application of the clamp. Therunners are formed with both sides alike, to embrace and slide on therail on both sides to allow the clamp to be used alike on both sides. Bythe runners of the clamp embracing the rail, the stave in the clamp isguided to be drawn correctly against the knife E, to shave the correctbevel or feather on the edge of the stave, while the taper is formingduring the y same time from the bilge to the ends of the stave, when thebead h1 with the depression in its middle is employed. Any degree ofbevel or feather may be made on the edge of the stave, accordingas theplane stock is placed above the rail, as the clamp will guide t-he staveagainst the knife, on the angle described by a line drawn from the faceof the plane stock to the face of the bead of the rail.

If the tool stock were made to slide, the clamp with the stave wouldhave to be held firmly againstV the bar L. The depressed bead of therail is only for winding-edged staves, as has been stated. The straightbead is for straight staves. The clamp is set against the movable braceM and drawn from it against the knife E until the exact taper and bevelis made. For light staves this is a most convenient and excellent modeof jointing.

This invention is very simple and makes excellent work. One knife forjointing staves is vfar better for that purpose than two.' The facilitywith which the staves can be jointed for any diameter of casks and thecorrect method of shaving the taper from the bilge, and the facilitywith which the staves can be put in and taken out of the clamp rendersthis invention very valuable to the art, as a great and importantimprovement.

Having thus explained my invention I claim- The plane stock of theointer formed with a depression in the middle for t-he purpose ofguiding the shaving plane E to shave the exact taper on the stave fromthe bilge on the middle to the end of the stave in the manner hereindescribed in4 combination f with the mode of producing a traverse taperor feather of any angle on the edge of the stave according to thediameter of the cask or barrels by the stave being held to the action ofthe shaving knife E by the combina-
